Sony VGN-SZ660N Battery
Your Sony VGN-SZ660N battery allows you to move freely about so that you can use it anywhere you please. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar to the old one. The more power the battery has, the longer you will be able to use the laptop on one charge. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What is important is the actual size of the battery and the connection it has.
Important clues of a failing battery
- The unit refuses to turn on when not connected to the charger
- The laptop lasts under 20 minutes while unplugged
- The battery gets puffy and looks like it will explode
